Specification of Letters Patent. l-Pat gnted N 29 1921 Application filed November 22, 1920. Serial No. 425,932.

To all whom it may concern:

Be it known that we, JOSEPH F. Gnnvnn and THOMAS S. Fox, citizens of the United States, residing at New York city, county of New York, and Brooklyn, in the county of liings and State of New York, have invented certain new and useful Improvements in Film-Holding Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to improvements in holding devices, and more particularly has reference to a holding device for printing films. In devices of this character small accurate adjustment at right angles are required and constant use of the device develops wear in the bearings which render accuracy very diflicult. One of the objects of this invention is to overcome this difficulty while at the same time preserving a simple, light, and accurate form of device which can be conveniently manipulated and carried around.

In the accompanying drawing, we have illustrated in Figure 1 in perspective, parts being broken away, a suitable form of film- "frame holder of the character described.

Fig. 2 is a plan view looking down upon the device shown in Fig. 1 in inverted position.

8 indicates a slide block of tapered form as shown, to the back of which is secured the bar 9 by any suitable means such as the.

screws 5. 10 indicates a filler secured through the wall of thebearing ll by screws such as 11 so that as the bearing 8 wears, the

'fille'r block 10 may be adjusted against the worn surface thereof by turning down on the screws 11. 12 indicates an extension from the bearing 4: against which the spring 13 is compressed between the same and the block 8 when the knurled thumb screw 14 provided with a protractor 15 is rotated,

thus permitting of accurate predetermined longitudinal movement of the block 8 and its bar9 which may be measured by the pointer 16 upon said protractor 15. 1718 are the usual pintles,the former a of which is resiliently projected by the coiled spring 19 under compression, and the latter of which may be projected by the knurled nut 20 with protractor 21 which may be read from the pointer 22.. 23 indi' cates a shoulder or projection from the housing or hearing at in the path of the longitudinal movement of the bar 9 serving as a stop therefor.

From the foregoing it will be readily ob; served that any longitudinal or lateral move simple, light, and easily manipulated device of. the character described in which practlcally all lost motion is avoided.

, Of course it will be understood that varlous modifications may be made in the construction and arrangement of parts without claimed.

We claim: 7 I

1. In a device of the character described, a bearing housing, and means in combination therewith for securing the same upon a departing from the spirit of the invention as j support, a slide bearing therein, and means i for taking up the wear thereof, a trans- .verse bar secured upon said slide bearing, a screw for shifting said slide bearing longitudinally and a resilient member for opposing the action of said screw.

y 2. In a device of the character described, a bearing housing, and means in combination therewith for securing the same upon a support, aslide bearing therein, and means for taking up the wear thereof, a transverse bar secured upon said slide bearing, a screw forsh1ft1ng sa1d slide bearing longltudinally and a resilient member for opposing the action of said screw, a pro ection from said housing for limiting the movement of said bar.

3. In a device of the class described, a

tapered channel housing and a bearing 1on-.

gitudinally adjustable therein, means in;

combination with said bearing for taking frame carrying means, means for shifting a up the Wear thereof, resilient backing for frame therein a predetermined distance. said bearing, and means for shifting the In testimony whereof We hereunto aflix 10 same'a predetermineddistance, frame carryour signature.
